Jay Ros Thank You for sharing this information.
I want DAC that works flawlessly with iPhone mini, if I remember right lightning dongle outputs is max 1.4 Vrms, it is more than enough for me and If you connect power hongry DAC with iPhone it doesn't work (correct me if I wrong on this).
It will be nice to know is someone use TANCHJIM Space or iBasso DC03Pro with iPhone mini?
Now I have only this question
TANCHJIM Space mentions output power 1Vrms (Unbal, low gain), but don't mention how to change gain. Is it via software or buttons combination and do it remember gain setting after disconnecting to from phone?
thanks
